Overview
The FiberXP® FR-STLCM2-150M Multimode ST to LC Fiber Ring OTDR Launch Cable is an essential tool for technicians using Optical Time Domain Reflectometers (OTDRs). By providing the necessary lead-in fiber, it allows the OTDR to overcome the initial dead zone, ensuring that the near-end connector of the cable under test is clearly visible and measurable.
Designed for field environments, this unit features a compact, lightweight ring configuration with a repositionable carabiner for easy attachment to technician gear. It is supplied in a durable pouch, housing 150 meters (492 feet) of 50μm multimode fiber with 1-meter pigtails. This design provides both a launch and receive cable solution, enabling complete link characterization from the initial connection to the final far-end termination.
